Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed April 26. 1907- Serial No. 370.477-

To all whom it may concern:

Be it known that I, BALTHASAR STEINMAN, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Rolling Window-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to window-screens and particularly to that class having the screen wound upon a spring roller attached to the window sill.

It has for its object to provide an improved screen of this kind which is simple in construction, can be readily attached to and removed from a window frame and from which the roller carrying the screen may be quickly removed for repairs.

The invention consists in the features of construction and combinations of parts hereinafter described and more particularly pointed out in the claims concluding this specification.

' In the accompanying drawings illustrating the preferred embodiment of my invention: Figure 1 is a front elevation of a window frame showing my screen applied, the upper part of the frame and window being broken away. Fig. 2 is a verticalsectional View on the line x-x of Fig. 1. Fig. 3 is a horizontal sectional view on the line y-y of Fig. l, and Figs. 4 and 5 are opposite end views of the screen removed from the window.

Referring more particularly to the drawings, 1 designatesthe window frame and 2 the lower window sash. The casing 3 containing the screen 4 is fastened to the window sill 5 by screws 6 passed through the front fiange 7 of said casing. The roller 8 on which the screen is mounted is provided with a round'lug 9 at one end engaging a round hole in one'end of the casing as shown in Fig. 4. The lug 10 on the other end of the roller is fiat and engages a slot 11 cut upward from the lower edge of the other end of thacasing as shown in Fig. 5. The roller is placed in the casing in the same manner as an ordinary shade roller is inserted in its supporting brackets. Said roller may be quickly removed for repairs, etc. by loosening the screws 6 and raising the easing far enough to allow the fiat lug 10 to drop out of its slot 11.

The upper edge of the screen is inclosed in a bent metal strip 12 to which is secured two lifts 13 preferably arranged one near each end. Said lifts are hinged to.

saidstrip 12 as shown and their vertical portions are provided with perforations 14 adapted to fit over lugs or pins 15 on the lower bar of the sash 2.

As shown in Fig. 1, the casing is of such length as to fit snugly between the sides of the window frame. The strip 12 runs between guides 16 which fit down upon the top of the casing whereby no cracks or openings are left through which insects may pass. flat and fits between the guides 16, it is necessary to hinge the lifts so that they may be connected to and disengaged from the lugs or pins 15 at will.

I claim:

As the strip 12 is 1..'.lhe combination, with a casing secured to a 'window of a screen-carrying roller having :1 lug extending into said v slot whereby said roller is retained in said casingand cannot be taken therefrom without removing said casing from the window sill.

3. The combination, with a window frame, of a casing secured to the window sill, a roller mounted in said casing, a screen wound on said roller, guides on the sides of said window frame a fiat strip secured to the upper edge of said screen and adapted to fit between said guides, and lifts hinged to said strip and having perforations adapted to engage lugs on the'bottom bar of the window sash.

4. The combination, with a window frame, of a casing fitting snugly between the sides of said frame, said casing having a flange along its front edge whereby it is secured to the window sill, a roller mounted in said casing, a screen wound on said roller, guides on the sides of said window frame and fitting down closely upon said casing, a flat strip secured to the upper edge of said screen and adapted to fit between said guides and lifts hinged to said strip and having perforations adapted to engage lugs on the bottom bar of the window sash.

In testimony whereof, I aifix my signature, in presence of two witnesses.

BALTHASAR STEINMAN.
